' PUMP.

Application filed October 27, 1923. Serial N'ol 671,089.

This invention relatesto new and useful in'iprovements in a pump.

Gne object of the invention is to provide a pump of the characterdescribed specially designed for the purpose of pumping fluids from wells, and vembodying means whereby a lubricant may be supplied when necessary between the traveling vvalve and the standing barrel. 4

Another object of the invention is'to'provide a pump including a surrounding jacket, a standing barrel therein, and a y'plunger arranged to work within the barrel, said pump also having a lubricant retainer around said barrel with ports through which the lubricant may be supplied to the interior of said barrel, and packing on opposite sides of said retainer between said barrel and jacket.

A still further feature of the invention resides in the provision of a pump of the character described, embodying means yfor adjusting said packing.

The lubricating system herein shown and described is also suit-able for use in .pumps of various designs, as well as in other form-s of mechanism embodying relatively movable parts.

With the above and other objects in View, this invention has particular. relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a sectional view of the upper section of the pump. Y

Figure 2 shows a sectional view of the middle section' thereof.

Figure 3 shows a sectional view of the lower end of the pump.

Figure 4 shows a transverse sectional view of the pump taken on the line 4-4 of Figure 1.

Figure 5 shows a transverse sectional view taken on the line 5--5 of Figure 2; and,

Figure 6 showsV a vertical sectional view of the jacket showing a side elevation ofthe barrel therein.

Referringnow more particularly to the drawings, wherein like numerals of reference designate similar parts in each vof the figures, the numeral 1 designates asurrounding tubular jacket whose lower end is internally threaded to receive the upper end of the tubular valve casing 2, The upper .end

of the tubing 3 is threaded into the lower endl of the casing 2, and this tubing usually carries the-well screen (not shown).

lVithin the lower end of lthe casing 2 `there is the valve seat 4 above which is the ball valve 5. provided to control said seat, and confined within the valve cage; said seat,.valve and cage constituting what isy commonly known as the standing valve of the pump. i i

The working barrel consists of a series of glandsL vintervening packing sleeves. rl`he lower gland is designated by the numeral-7, and is sleeve-like in form, having the external annular flange 8 at its upper end, which rests on the internal annular shoulder 9, formed vwithin the lower end of the jacket. 'The upper gland is indicated 'bythe numeral 10,*anvd fits within theupper internally threaded end of the jacket, and has its V'upper end enlarged'into an externally threaded head 11, whichfis screwed into said upper endV of said jacket. The fluid con-duit pipe'1-has its lower end threadedinto theupper'en'd of the jacket.l

Between said glands 7 and 10 are the packing sleeves 12 and the perforated sleeve-like glands 13.

Within the working barrel, vabove described, thereis the plunger 14. This plunger is tubular and the passageway through it is controlled. at its Vupper and lower ends bythe ball lift valves 15 and 16, confined within suitable cages 17 and 18, respectively. The cage 17 has the upwardly diverging ports 19, 19, and to the upper end of said cage, the lower end of the sucker rod 2() is attached. The plunger is reoiprocated up and down in the usual way through this sucker rod. The cage 17, yand consequently the sucker rod 20, has a swiveling connection with the plunger. In order to provide this swiveling connection there is a tubular thimble 21 whose lower end is threaded into the upper end of the body of the plunger and the upper end of this thimble has an external annular fla-nge 22, forming a head. Surrounding this thimble and fitted loosely between the flange 22, and the upper end of the plunger body there is a gland 23 whose lower end has an external annular flange 24.

There is a tubular nipple 25 whose lower lits against .the upper end of said head 22. The upper end of the nipple 25 is reduced and threaded up into the cage 17, and serves to connect the nipple to said cage as well as to clamp the valve Aseat 27 of the valve l5, in place. y

It may be here stated; that the head ll of the gland 10 has a sw'iveling connection with said gland, and the upper end of said head has a polygonal socket 2S, provided to receive a correspondingly shaped external ei'ilargement 29, formed on the nipple 25 intermediate its ends.

Each of the glands 1'3 are sleeve-like in form, each having the external, annular end flanges, 30, 30, which fit closely within the jacket l, forming the lubricant chambers 3l which are filled with a suitable lubricant, as hard oil or grease. These chambers are filled through the inlet ports 32, and are dra-ined of waste through the outlet ports 33, said ports leading through said jacket at the upper and' lower ends of the said chambers 3l, respectively, and being normally closed by the removable plugs 34 and 35, respectively.. The glands 13 are perforated, as shown topermit the lubricant to work through between the plunger and standing barrel for lubricating'the same. While oil is being pumped, the oil itself will usually work its way in between the plunger and the pump barrel and suiiiciently lubricate the pump, but if the well is dry, or if the oil should stop flowing, the lubricant in the chambers 3l will then lubricate the pump as above explained. Y j

The lubricating system described may also be employed for lubricating cylinders of any character, having a traveling piston,

or plunger therein, and for all similar purposes.

In case the packing l2 becomes worn, permitting it to leak, the sucker rod may be lowered to seat the enlargement 29 in the socket 28, and then turned to screw the head and applications or' the construction herein described may be made without departing from the principle oit' the invention, and I hereby reserve the right to make such mechanical changes and adaptations as may be comprehended within the scope of thel appended claim.

`What I 'claim is:

A deep. well pumpk including a jacket having` a lowerY internal abutment, a barrel formed of alternately arranged cylinders and packing sleeves and resting on said abutment, a plunger in the barrel, some or said cylinders being formed with annular outside fianges spaced apart to form a lubricant chamber between them, said cylinders havinglubricant ports leading from 'said chambers to the interior of the cylinder and said jacket having an upper and a lower port communicating with some of said chambere, and a removable upper abutment i-n the jacket abutting theA upper end of the barrel. In testimony whereof I have signed my name.
